The two cables are attached at the respective front and rear ends of the hood 9 and are brought together centrally thereof and passed through a guide block 18. From the guide block 1S the elevating cable 13 passes upwardly and over the pulley 19 on the shaftgl, thence downwardly and under the second guide pulley 20, and is attached to a lever 21 pivoted at the front of the vehicle where it is readily accessible for use by the driver of the vehicle. The lever may be manually actuated or pedal operated, and it will be apparent that by pushing the lever forward in Figure 1 the elevating cable 13 will be instrumental in lifting the hood, and the burning apparatus carried thereby. rlhe apparatus is bodily lifted, its movement be ing guided by the action of the slide sleeves or collars on the posts and the counterweight balances the load so that only slight power is required for moving the hood. l/Vhen not in use the hood is elevated, but when desired for use, it is lowered by releasing the elevating lever, and the weight of the apparatus, which slightly overbalances the counter weight, causes the hood to descend to proper position.

The burner apparatus travels over the sur- Yface of the ground at the proper elevation,

and as seen in Figure 2 follows a path at the side of the roadway or pavement.

Vithin the top of the hood are affixed oil burners 22 each having an oil pipe 23 and an air pipe 24, and the burners are each provided with a nozzle or flame projector 25, located beneath the top of the hood. The burners are arranged in lateral rows, four to a row, as indicated in Figure 5, and as seen in Figure 1 there are five rowsof four burners each. The branch air-pipes '24 from the burners are connected to a main air pipe 2G that is provided with a control valve, and the branch oil-pipes 23 are connected to a main oil pipe 28 having a control valve 29, and these main air'a-nd oil pipes are connected with the air pump and tank respectively, as by flexible connections, to permit Y movement of the burner apparatus.

Within the hood, and just below the flame projectors or nozzles is located a horizontally disposed grid-frame 30 that is designed to protect the nozzles and prevent contact therewith from any objects passed over.

The hood is provided with end and side walls that are readily. ieXed or moved as they encounter obstructions in the path of the apparatus, two side plates 31 being shown, one at the inner side and one at the outer side of the hood. These plates are suspended from longitudinally disposed hinges 32, and are fashioned with curved, projecting front ends 33. They are designed to swing laterally and upwardly from verti cal position, as indicated by dotted lines in Figures 2 and 3, should they encounter a stone or other obstruction, and their curved front ends permit them to ride over such a stone in order to prevent breaking.

The hood, and plates 31, are preferably of metal, or may be of other ireproof mate-V rial., designed to confine the projected flames within the area below the hood, and at the front and rear of the hood are additional narrow plates 34 and 35 respectively that are hinged transversely of the hood at 36. These plates or flaps 341 and 35 are comparatively narrow and arranged in suitable nun1- bers in rows on their hinge rods in order that one or more of them may be swung upwardly to permit passage over an obstruction of the hood. Thus the flexible side plates andthe flexible end flaps form a rectangular shield, below the hood, for confining the action of the projected flames from the burners to the area traveled over by the apparatus, and the flexible elements, should they encounter an obstruction, are readily swung out from danger of breaking by contact with stones or other obstructions.

At the front end of the hood, a series of longitudinally disposed, upturned, curved plates, which may be of resilient material, as 37, are attached to the hood as a guard.' These guards are designed to ride up over any obstruction that may be encountered, and elevate the hood to bring the burners and the hood to position where they may safely pass over said obstruction, it being understood that the suspended hood may thus be elevated in connection with its counterbalancing weight 17.

From the above description taken in connection with my drawings it will be apparj ent that I have provided an apparatus of this character that may with facility be adjusted vertically with relation to the ground or the vegetation that is to be removed by burning, or the apparatus may with equal facilitybe elevated out of operative position when not required, and be transported as a part of the automotive vehicle. The projected flames may be regulated and controlled, and under pressure are directed to the vegetation to be destroyed in order that the area passed over may be thoroughly cleaned or cleared. The apparatus is so constructed and equipped that it is protected from fracture or breaking by the use of the flexible side plates or wings andthe front andvrear flaps, while the guard runners 37 form fenders and guards for the purpose described.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is: K
